Horizon Report 2012: libraries a challenge, how will tech advances help?

One of the 5 “significant challenges” that serves as the framework for the Horizon Report 2012 is the effect that social networks, new publishing paradigms, and out of date business models have on the library’s traditional “role as curator”. However I didn’t see any discussion of how the 6 technologies discussed would impact that issue in significant ways. People want to have access to everything in digital format and tablets and mobile apps certainly make viewing those things available that way more convenient, they mentioned some museum projects with RFID to control inventory, but the only other mention I saw of the library specifically was the cite of the Chronicle blog post about having libraries responsible for collecting, arranging, preserving and making available a wide selection of games. Which seems to be going the wrong direction?
